And to add on, the Mirror Coat set is just for shock value, but its niche is too specific to be ranked.

I think we have discussed about Milotic many times already, including on why it is unranked. As Ninjawarrior said, it is outclassed by numerous Water-types. It is directly outclassed by Toxapex in every way (Defense, ability, movepool, typing), except that Milotic can deal some damage and hit some Dragon types with Ice Beam, but its niche is too small to be ranked. I also don't think Marvel Scale is a niche over Toxapex though, since Milotic despises Toxic anyway and Toxapex cannot be affected by it, even furthers Toxapex's use over Milotic.

Once again, 80-90% of Pokemon has some kind of niche. Some of them have solid one, such as Muk-Alola in being a rare counter to Hoopa-Unbound and its ability to Pursuit trap and beat special attackers. While some others' niche are negligible like Delibird, which is the only Pokemon in this game that can learn both Defog and Rapid Spin but the niche is extremely miniscule.

Sorry to say this, but I may do "blacklist" system like Smogon does sometimes. For this thread, I may blacklist a Pokemon that is discussed for more than 2 times and doomed to failure. I think Milotic is being discussed for a lot of times too and also never had real productivity.
